Description

HotImageIndex is a TImageIndex property with the ordinal position for the bitmap displayed on the button when it is hot (under the mouse cursor - hovered). It refers to the position in the Images property where the associated image data is stored. The default value for the property is -1, and indicates that an explicit value has not been assigned to the property.

The Lazarus IDE provides a property editor that allows selection of one of the Images from a drop-down image list. The position for the selected image is stored as the property value in the Object Inspector.
